We continue experimenting with patterning different types of fibers. When fine insulated wire is embroidered onto a piece of linen tape and supplied with a current, it interacts with magnets. Two sets of embroidered coils, one on top and one on the underside of the tape in this video, pull the tape to the left …

Tumbling tumbleweed
In an effort to create tiny holes in our molded rubber parts, we made these small salt crystals by adding concentrated saltwater to alcohol, which is a poor solvent for salt. Right away, it starts to snow 25-micron cubes. The cubes are added to liquid rubber, then dissolved out in water, creating voids–an approach that …
Fall 17 class roundup
The latest batch of ECE 412 (Embedded Systems) projects is now online. Check out the LED sign that now adorns our lab, the duct-tape based CyberHand and the sound-controlled ping pong tubes. The 14 projects also included a sorting hat, plus a different kind of sorting system based on a pressure sensor. While cardboard and …
Athletic tape that tracks your moves
Check out wireless optical stretch sensors in action in this video. We embedded a strain-sensitive elastic optical fiber into a piece of sticky, stretchy athletic tape that can track muscle stretching in real time. There is a single “U-turn” shaped fiber along with a detachable wireless module that can also collect acceleration and orientation data. …
Fiber tutorial up at Soft Robotics Toolkit
Our tutorial is up at the Soft Robotics Toolkit website. It covers how to use an embroidery machine to add a patterned fiber layer to a 3D print, a circuit board, or a thin laser-cut part. It also describes how to use a 3D printed template for installing fibers that are too thick for the …
